WhatsApp Introduces Passwordless Chat Backup Encryption
WhatsApp users can now protect their chat history with biometrics instead of remembering passwords.
A new passkey-based encryption system allows users to secure their chat backups using biometrics or screen locks rather than lengthy passwords or cumbersome encryption keys.
The feature, available on iOS and Android, enhances backup privacy by relying on cryptographic key pairs – a private key stored locally on the user’s device and a public key shared with the app.
This design prevents credentials from being exposed in data breaches, as the private key never leaves the device.
Users can now encrypt backups with a fingerprint, facial recognition or a simple device PIN, unifying backup security with the same protection used for personal chats.
The feature can be enabled via Settings -> Chats -> Chat Backup -> End-to-End Encrypted Backup, where users will find the new passkey option.
